The growing trend toward bring your own device(BYOD) in the workplace is putting company data at risk, according to a survey by Mozy and Compass Partners. Most (87 percent) small and midsize businesses have no formal policy in place regarding employees’ use of personal devices for work purposes — and 80 percent weren’t even concerned. About 33 percent of companies let employees make their own decisions about how to back up company and client data on their devices, and most companies lack adequate backup or data recovery plans for those devices.
Besides not backing up, employees are engaging in other risky behavior with their personal devices, including not having antivirus protection, leaving laptops alone in coffee shops or other public places, using public computers to access company networks and transferring unencrypted data.
Why it matters to your business: The risk of loss isn’t just theoretical. For example, 11 percent of the survey’s respondents said employee laptops have been stolen in the past, and in 98 percent of those cases, all of the lost data was never recovered. The “bring your own device” trend isn’t going away, but if you allow it, you do need to set some rules to protect your customers’ data, your data — and your business.

Before you start to fix a hard drive, make sure you have an up-to-date backup. After that, let us do some simple diagnostics and repairs. Both Windows and Mac OS come with built-in hard-drive utility that scans your hard disk for errors and attempts to fix them.
For Windows
1. Double-click on My Computer to open the My Computer window.
2. Select the Drive that you want to diagnose and repair.
3. Choose Properties from the File menu. You should see the Properties window for the drive that you selected.
4. Choose the Tools tab.
5. Click the Check Now button under Error Checking Status.
6. Depending on your version of Windows, choose either “Thorough” or “Scan for and Attempt Recovery of Bad Sectors.”
7. Click on Start
Computer hard Drives may fail or crash. One of the common causes is a computer virus, it may have corrupted or broken your computer system. Here is a way to fix a hard Drive that has crashed.
1. Look for tell-tale signs that your computer is about to crash or fail. Extreme slowness, repeated blue screen and noise or clicking are sometimes signs that your computer hard drive is about to crash. When you hear the sound of clicking, scraping or grinding, immediately turn off or shut down your computer. Doing so will prevent any loss of data.
2. Power down and then power up. Sometimes, hard drive crashes can be easily recovered by doing a power shutdown of the computer. Then, after waiting for a couple of minutes, power it back up again. The initial hard drive crash may not be too serious, but if it happens often, start performing a full system backup, if you haven’t been doing so, to be able to recover your data should the inevitable happen.
3. Ensure that your hard drive and other internal components are seated properly. If Steps 1 and 2 do not work, you may need to open your computer’s CPU to check on some of the drive connections. Sometimes connections get dislodged, especially if you move your computer box often. The symptom will manifest as if the hard drive has crashed, giving you a “Drive error” when you try to boot up your computer. First, turn off your computer and unplug it. Then remove the case of your computer box. Press on each connector to connect it properly. Put the cover back again, plug the computer and power it back up.
4. Insert your boot disc and try to boot up your computer using the disc. Once you are able to do so, you can reinstall your operating system. After installing your software, proceed to perform data recovery using your ghost CD or backup.
5. Use an emergency repair disc to get your computer to work again. Then restore from the last known good configuration.
6. Reinstall your operating system using the installation or system restore CD that came with your computer when you first purchased it. It will take you through a series of steps that include formatting your hard drive, which will then erase your data. Do this as a last resort.
7. Recover your data by using a restore and recovery software or using your most recent backup after you have reinstalled the operating system in the previous step.
8. Reinstall your applications that did not come with your computer when you bought it. Some examples would be Adobe Photoshop, anti-virus software and movie-making software.
A hard Drive is a computer storage device that manages and organizes computer data from the actual CPU. The hard Drive also stores all critical system data required for a computer to startup. Without a hard Drive, a computer cannot function. Fixing a locked up hard drive that prevents a computer from functioning is an important aspect of computer maintenance and repair.
1. Check that the computer hardware is plugged into a reliable power source. Turn on the computer.
2. Hold down the “F2” key on your keyboard if you’re using the Microsoft Windows operating system. If using the Mac operating system, hold down “Option-Command-Shift-Delete” on your keyboard.
3. Use your keyboard’s arrow keys to select “BIOS Setup Menu” in the screen that appears (Windows OS). If using a Mac, wait for the startup bypass process to finish and use your keyboard’s arrow keys to select a primary startup volume.
4. Select “Hard Drive Priority” in your Windows BIOS system, or your main hard drive in the Mac operating system.
5. Check that your boot hard drive is listed on the top of the boot-up list (applicable in both PCs and Macs). In Windows, continue further by selecting the “Disable Hard Drive Auto-lock” option in the BIOS system screen.
6. Save and exit, allowing the operating system to boot-up. This will clear any system errors causing the wrong hard drive to lock up.
As with any piece of electronic equipment, plenty of things can go wrong with an external hard drive. There are two types of problems: hardware and software. Hardware problems are physical flaws that prevent the Drives from spinning and accessing data. Software problems are digital mixups that make retrieving data more difficult.
1. Figure out whether you need a hardware or software fix. Look for grinding sounds from your drive or humming that starts or stops. These are signs that the actuator arm and discs are no longer in alignment and your drive is timing out. If it seems as though nothing is wrong with your hard drive, it’s probably time for a software fix.
2. Run one of the many software fixes, if you think the problem is related to software. These programs feature on-screen directions, making it easy for you to progress through them. If this works, you don’t need to fix a physical problem.
3. Remove the many tiny screws that holds the drive together. Eventually, you’ll get to the innards of your drive. Be very careful not to bend or force a piece to go where it doesn’t want to.
4. Determine if you’ve set things straight. Look to see whether anything was loose inside your external hard drive. If you have recently dropped it or traveled with it, it is possible that something came loose. Also check that all the arms and platters are straight and do not appear bent in any way. If they are bent, straighten them with your hands or pliers.
5. Put everything back together and check that everything in your external hard drive is working properly.
6. Try using the external hard drive on another computer. Maybe your computer or USB port is the problem and needs replaced.
Like cars, computer parts can give out when you need them most. The hard drive is one of the most important computer components. Luckily, it gives warning signs before a complete crash. “Bad Sector” or “Read/Write Errors” warn that the hard drive is failing. It is important to back up your important data at least once a week.
The hard Drive Makes No Noise, or Powers on and Makes a Grinding Noise
1. Open the computer and remove the hard drive. Find and remove the drive’s logic board. Inspect the area underneath the board. Look for signs of other damage.
2. Replace the board with the logic board from an identical working hard drive. If you find more damaged areas, just replace the entire hard drive.
3. Test the repaired drive.
The Hard Drive Powers on and Then Goes Silent
1. Separate the logic board from the hard drive. Ground the hard drive to an electrostatic point.
2. Replace the logic board and re-install the hard drive.
3. Boot the hard drive. If successful, immediately back up all data. Disk utilities, like ScanDisk, can move data from bad sectors to undamaged areas. This is only a temporary solution-the drive will fail again.
4. If the drive does not boot, you will need to make it a secondary drive in a different computer. Change the jumpers from “master” to “slave” position. Use Data Recovery Software to transfer your data.

I was thinking about going down the RAID road with my rig and was wondering what people think is best RAID-0 or RAID 0+1(This is what i was thinking) or is there a better option advice would be well recived befor i go spend £150 on 3 more new drives to make the 4 needed for 0+1 and could you tell me how RAID 0+1 and RAID 1+0/10 differ please.
As was said up, it’s necessary to know the application before accurate advice can be given. RAID 0 will benefit you in database access, huge spreadsheets, video editing, CAD rendering and a few other specialized apps. For everybody else, all its going to do for you is getting you bragging rights for good benchmark scores.
If you need data redundancy, and in reality who doesn’t, RAID 1 is a viable solution. For most data control situations an NAS presents a very convenient alternative and it easily performs the same job for multiple boxes. All data can be kept on the NAS with images of a standard “programs drive” as well as individual boot drives for each machine on the network, making cold metal restores a cinch. Many proprietary RAID formats will even allow ya to do rebuilds and expansions on the fly via “Hot Swap”. It’s also rather “portable” and the joke in my SOHO is that in case of fire, I can grab the NAS handle and run …. and after the data is safe come back in for the any employees, wife, kids, etc.
If your concern is only “one box”, RAID 1 provides data redundancy…..but so do other alternatives …. i.e. tape / optical, cloud backups …… RAID 0 , again unless you have specialized applications, will serve no observable benefit other than nice benchmark scores.

Pandora Recovery is a powerful free tool that provides its users an effective way to attempt recovery of permanently deleted files. And that does not mean restoration of a file from Recycle Bin. Pandora Recovery actually recovers files permanently removed from Recycle Bin, files originally deleted using Shift + Delete keys bypassing Recycle Bin and files deleted from DOS prompt.
Pandora Recovery is not a backup tool – it can recover files that have been deleted months before Pandora Recovery was installed. And while the likelihood of successful recovery is negatively affected by the time passed since the deletion of files Pandora Recovery users were able to recover files eleven years after deletion and more than five years after re-formatting a hard drive!
Features:
1. Browse, Search, Preview and Recover deleted files
Pandora Recovery allows you to find and recover recoverable deleted files from NTFS and FAT-formatted volumes. Pandora Recovery will scan your hard drive and build an index of existing and deleted files and directories (folders) on any logical drive of your computer with supported file format. Once the scanning is complete you have full control over which files to recover and what destination to recover them to. You can BROWSE the hierarchy of existing and deleted files, or you can use SEARCH functionality to find a deleted file if you remember at least one of the following:
– full or partial file name,
– file size,
– file creation date, or
– file last accessed date
On top of that, Pandora Recovery allows you to preview deleted files of certain type (images and text files) without performing recovery. This feature becomes really important if you are forced to recover deleted files to the same drive. Currently you can preview files having several image file types (BMP, GIF, JPG, PNG, ICO,TIF, TGA, PCX, WBMP, WMF, JP2, J2K, JBG, JPC, PGX, PNM, RAS, CUR) and several text file types (TXT, LOG, INI, BAT, RTF, XML, CSS). Quick Viewer allows you preview file contents as text if it cannot find appropriate viewer for it. To use quick viewer you can select deleted file and or click the Quick Viewer icon or right click on deleted file and select ‘Quick View’. Quick View will then display a preview of deleted file.
Finally, Pandora Recovery allows you to recover deleted files, without any limitations on application’s end. Note that successful recovery might not be possible – if the original location has been reused by operating system to store different content the integrity of the original content has not been preserved and the recovered data will most likely be corrupted.
2. Surface (cluster) scan
Surface Scan – Embedded Image Preview
Click Image to Enlarge
As of version 1.1.20 Pandora Recovery implements surface (cluster) scan of targeted media, which allows:
– recovery of files whose MFT record has been reused by OS,
– Recovery of files from reformatted media,
– Recovery of files from discs with damaged or missing file allocation table.
Disk surface scan enumerates all unused clusters on the disk drive and searches for disk areas probably occupied by the data of removed files. Using this method of search, we do not use information contained in the file allocation table. So, it can work even on reformatted disk drives (except in) the case when low-level formatting was performed).
Almost each type of files has its unique features, for example the beginning of a JPEG file always contains JFIF magic word. Using this information we can determine what areas of the disk may contain deleted files data. Knowing the structure of a file (which is common within one file type) we can determine the length of the file and then recover file data.
File name and file attributes information are stored separately of the file data in file allocation table (FAT in FAT32 file system, MFT in NTFS), so we cannot determine the name of the file, its attributes, file path and recover data of file alternative data streams.
This method works only with non-fragmented files. Data of non- fragmented file(s) are stored in contiguous neighbor clusters, while data of a fragmented file may be stored in different places of the disk.
Remarks: In NTFS small files (less than 1KB in size) reside only in the Master File Table (MFT), so we cannot find such files using the Surface Scan Method.
3. Recover Archived, Hidden, Encrypted, Compressed files
Pandora Recovery can recover not only ‘regular’ files, but also archived, hidden, system, sparse, encrypted and compressed files.
Windows 2000 introduced Encrypting File System (EFS), which supports file encryption. EFS service runs on top of NTFS and encrypts or decrypts files or folders transparently for users and applications. Pandora Recovery does not decipher contents of encrypted files. Instead of that it copies the content of an encrypted file in raw mode just like data back-up applications do.
Encrypted and compressed files will be color-coded once drive indexing has been completed. Names of the encrypted files will be displayed in GREEN, while compressed files will be BLUE.
4. Recover Alternate Data Streams (ADS)
In NTFS all files have at least on file stream also called the unnamed $DATA stream. The unnamed stream contains the actual data of the file. Alternative streams usually contain file-related metadata. For example, MP3 music file may contain unnamed stream, where data are stored, and one or several additional streams where composition genre, album name and author’s name are stored.
While file might be usable without the original content of its Alternate Data Streams this useful information should be recovered. Alternative streams often contain file metadata, while file attributes contain information about how files are displayed in Windows Explorer.
5. Recover Images, Documents, Movies, or any other type of files
Pandora Recovery handles files regardless of their type, size or any other attribute. As long as the space on the logical drive has not been reused by operating system Pandora Recovery can successfully recover content of any deleted file.
If you want to search for unspecified deleted images or movies the best strategy is to search for common file extensions:
– *.avi, *.mpg, *.mov for video
– *.bmp, *.jpg, *.png, *.gif for images
6. Recovery success estimate
When a file has been deleted, the disk space occupied by the file can be reused by file system. The file system can reallocate this space for data of newly created files. Once operating system does that the deleted file becomes partially or completely overwritten. There are more chances that an overwritten file is corrupted and can not be recovered successfully. Overwritten files can still be recovered, but they likely will not be usable.
If clusters once used by a file have been reused by another already deleted files Pandora Recovery will display 0% as ‘overwritten’ value, which means the clusters are not currently in use. Still, the recovered data is likely to be corrupted.
Pandora Recovery gives you an estimate of recovery success by displaying the percent of clusters reused by operating system. To view the estimate move the mouse pointer over a file for a second or two until popup tip is displayed. The tip will say “Overwritten: 50%” or “Overwritten: 0%” . The higher the percent, the lower the chance of successful recovery.
Names of files with partially or completely overwritten clusters are displayed in RED.
7. Review File properties and Drive properties
Pandora Recovery displays properties of files: file type, deletion status, percent of clusters reused (‘overwritten’ attribute), path and size of the file, date created and date modified and common attributes (compressed, archived, hidden, system, encrypted…). To display file properties you should right-click on a file and select ‘Properties’ from context menu.
Pandora Recovery also displays properties of available logical drives: Drive letter, volume label, type, file system, total and available size. To display drive properties you should right-click on a logical drive and select ‘Properties’ from context menu.
8. Recover to Local Hard Drive, Network Drive, or Flash Drive
Pandora Recovery can use local hard drive, remote network drive or flash drive as a recovery destination folder. Pandora Recovery even allows you to recover deleted files on the same drive that the deleted files resided on originally.
IMPORTANT! To increase the success rate of file recovery it is strongly recommended that you recover your deleted file to a secondary hard drive, a network drive, USB Flash drive, or other external media. While recovery to the same drive that the deleted files reside on is physically possible it may lead to partial or complete loss of your deleted content. Non-deleted files will never be put at risk in either circumstance.
If your lost data resides on your C: it is recommended you perform your file recovery by physically removing the C: drive from your computer and attaching it as a slave on another computer and then performing the file recovery using that other computer.
9. Recognizes FAT16, FAT32, NTFS, NTFS5 and NTFS/EFS
NTFS (New Technology File System) is the default file system in all modern operating systems from Microsoft, such as Windows NT, Windows 2000, Windows XP and Windows Vista. NTFS 5.0 is improved version of NTFS introduced with Windows 2000.
NTFS replaced Microsoft’s previous FAT file system, used in MS-DOS and early versions of Windows. NTFS has several improvements over FAT such as improved support for metadata and the use of advanced data structures to improve performance, reliability, and disk space utilization plus additional extensions such as security access control lists and file system journaling. The exact specification is a trade secret, although (since NTFS v3.00) it can be licensed commercially from Microsoft through their Intellectual Property Licensing program.
NTFS5 (where 5 comes from internal enumeration of Windows 2000, the operating system which first implemented NTFS v.3.00) includes several new features over its predecessors: disk usage quotas, sparse file support, reparse points, distributed link tracking and file-level encryption, also known as the Encrypting File System (EFS).
FAT16 based on the usual 512 byte sector size and used with MS-DOS and Windows 3.xx, has a maximum partition size of 2 Gigabytes. FAT16 does not natively support alternate data streams or file permissions and it is not a journaling file system.
FAT32 was introduced with Windows 95. It is the standard file system used in Windows 95/98/Me. The theoretical Maximum partition size for the FAT32 file system is 8 Terabytes. However, in Windows 95 and 98 the size is limited to 127.53GB because to the disk 16-bit disk utilities included with the operating systems. Windows 2000 and later operating systems should be able to support the theoretical maximum size of FAT32, but Microsoft has placed an artificial limit which only allows formatting up to 32GB volumes on Windows 2000 and XP. The Maximum file size that can exist on a FAT32 formatted partition is 4GB. This has become a major factor in rendering the FAT32 file system obsolete for use on a personal computer hard drive. Media files can easily exceed this maximum size. FAT32 does not natively support alternate data streams or file permissions and it is not a journaling file system.
10. Compatible with Windows Vista, Windows XP, Windows 2003 and Windows 2000
Pandora Recovery requires Windows 2000, Windows XP, Windows 2003 Server or Windows Vista for installation. Pandora Recovery currently only recovers deleted data from NTFS formatted drives. There are no plans at this time to create a version compatible with the Mac, Linux, or any other non-Microsoft Operating System.
11. Wizards, hints and context-sensitive help
An easy way to get started in recovery your deleted files is by using the Wizard. By default the Wizard will open automatically when you start Pandora Recovery. You can also access the Wizard by clicking on the wizard icon in the program toolbar.
How does it work?
When you delete a file on FAT32 or NTFS file system, its content is not erased from disk but only reference to file data in File Allocation Table or Master File Table is marked as deleted. It means that you might be able to recover deleted files, or make it visible for file system again.
